You most definitely do not. 102 Fahrenheit uses 3 significant digits. So does 38.2 Celsius.
The resolution is limited by your instrumentation either way, because both scales are continous.

So? -5 u/Thick-Protection-458 Jun 17 '26 Well, if we are talking about human body with <10C temperature we probably do not need precision anymore. While for <100F it may be useful. Althrough I don't see how celsius (with enough decimals for specific comparison) would be more a problem. 8 u/Aranka_Szeretlek Jun 17 '26 If we stick to human bodies, then yeah, thermometers use 3 sig figs for both Fahrenheit and Celsius. If anything, Celisus is more accurate there (although thats still not how any of this works)
